Fannie Mae reports that for all of 2013, it provided $28.8 billion in multi-family finance, involving about 507,000 multi-family units all together. Almost all of last year’s total — $28.5 billion – was delivered through MBS execution, and the GSE also says that it met the Federal Housing Finance Agency’s mandate to reduce multi-family volumes by 10 percent relative to 2012 levels.

According to Jeffery Hayward, head of the company’s multi-family mortgage business, more than 85 percent of the multi-family units financed by Fannie Mae last year were affordable to tenants earning at or below the median income in their area. Financing for rent-restricted properties (and properties receiving other federal and state subsidies) was $2.3 billion, a decrease from 2012’s $3.8 billion.

Also in 2013, large loans ($25 million or higher) totaled $10.4 billion, down from $11.6 billion in 2012, while small loans (up to $3 million, or $5 million in high-cost areas) totaled $2.3 billion, down from $3 billion in 2012. Loans for seniors housing were $1.6 billion, up from 2012’s total of $1.2 billion, and loans for manufactured housing also saw an uptick from $912 million in 2012 to $1 billion in 2013. Student housing came in at $454 million, a decrease from $712 million in 2012.

Also in order of production volume are the top six producers last year for affordable housing: Wells Fargo Multifamily Capital, Oak Grove Capital, Greystone Servicing Corp., Walker & Dunlop, Citibank, and PNC Real Estate. The last two tied for fifth place.
